Title: Improvements in or relating to static multi-state circuits incorporating transistors
IPC: H03K3/286
Filed: 1957-12-04
Abstract: 878,296. Transistor multi-state circuits. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 4, 1957, No. 37732/57. Class 40(6) Two transistor logic circuits of the type described in Specification 878,295 and comprising a plurality of input terminals connected to the base of the transistor through respective input impedances of identical value and having an output terminal connected to the collector are arranged to form a multistate circuit by connecting each output terminal to one input terminal of the other circuit, Fig. 1 shows a bistable circuit comprising two cross-coupled "NOR" circuits, that is, two circuits comprising a plurality of input resistors 17, 18, 19 connected to input terminals 14, 15, 16 and to the base of a transistor which provides an output voltage at the collector only when all input signals are zero. On the application to lead 31 of a negative pulse, both transistors are rendered conducting so that the output signals from both the collector circuits are brought to zero. At the end of the pulse one or other of the circuits remains conductive and the other is cut off. By connecting terminal 14 to 16 and 14<SP>1</SP> to 16<SP>1</SP> through capacitors the conducting state will alternate when each pulse is applied. (Fig. 2, not shown). Alternatively, by connecting a capacitor between the collector of one transistor and respective input terminal 14 or 16<SP>1</SP> it may be arranged that the circuit returns to its previous state upon the cessation of the input pulse to lead 31 (Fig. 3, not shown). By connecting terminals 15 and 16 through a capacitor and by inserting a capacitor in the connection between the collector of transistor 10 and base of transistor 10<SP>1</SP> the circuit is such that upon cessation of a pulse on lead 31 the circuit returns to a state in which transistor 10<SP>1</SP> is conductive but upon the charging of capacitor 32 to a sufficient value the circuits revert to the opposite state (Fig. 4, not shown). Reference has been directed by the Comptroller to Specification 845,371.

Title: Improvements in or relating to coupling circuits for amplifiers
IPC: H03F3/22
Filed: 1946-12-24
Abstract: 626,143. Impedance networks. GARLICK, J. Dec. 24, 1946, No. 37805. [Class 40 (viii)] In a coupling circuit including a transformer, the inductance Zc of the latter forms a shunt element of a high-pass filter circuit terminated at both its input and output ends by resistances R1 and R0. For mathematical convenience the actual transformer is not shown, but its effect is represented by adding an ideal imaginary transformer IT at the output terminals. In some constructions the output may be connected across the condenser ZA in series with the resistance R0 to improve the response at low frequencies. The presence of the resistances R1 and R0 enables the imput impedance of the network to be brought into a desired relation to a further impedance in the apparatus in which the circuit is included.

Title: Apparatus and method for embossing a pattern upon a sheet of  imitation leather
IPC: B68G11/04
Filed: 1972-08-16
Abstract: 1396573 Sheet forming T SAITO 16 Aug 1972 [19 Aug 1971 (2) 15 Oct 1971 21 Dec 1971 18 Feb 1972 24 May 1972] 38295/72 Heading B5A [Also in Division B6] A sheet 3 of plastics material made in imitation of leather is embossed against a member 2 bearing a pattern of grooves 11 by introducing a heated fluid (e.g. air) under pressure into an open ended pressure vessel 1 which is in sealing engagement with the rear surface of the sheet 3. The vessel may be divided by an apertured plate 9 into chambers 4 and 5. The chamber 4 is provided with a fluid inlet 6 and electric heaters 8, and the chamber 5 with an inlet 7 for fluid under pressure. Cooling fluid, e.g. water may be circulated through passages 10 and 13. In an alternative form, Fig. 2, the pressure vessel 21 is a single chamber 26 with an inlet 25 for heated fluid under pressure. The embossing member 22 is shaped to deform as well as emboss the sheet 23. Suction passages 30 may communicate with the grooves 28 of the embossing pattern. Before embossing, the passages 30 may be charged with heated fluid under pressure to force the sheet 23 away from the embossing surface to thereby render the sheet more pliable. A reinforcing material (e.g. glass fibres or fibres of non-woven cloth and a binder) may be sprayed on to the unembossed surface of the sheet, whilst the sheet is still in contact with the embossing member (Fig. 5, not shown). Alternatively a cloth-like or elastomeric material may be bonded to or coated on the unembossed surface. A foaming plastics material (e.g. a urethane resin) may be injected into the downwardly deformed recess portion of the sheet to provide a resilient cushioning (Fig. 4, not shown). The process may be applied to a web of imitation leather which is advanced intermittently through an embossing device of the type shown in Figs. 1 and 2. The imitation leather sheet may comprise a vinyl coated fabric.

Abstract: 915,955. Starting prime movers. C.A.V. Ltd. Oct. 11, 1961 [Nov. 9, 1960], No. 38441/60. Class 38 (4). Relates to engine-starting apparatus comprising a solenoid 1 for effecting initial engagement of a motordriven pinion with a toothed wheel on the engine, such initial engagement serving to close contacts 3 and energize motor 4 through resistor 5. The rotation of the motor shaft causes the pinion to be moved into full engagement with the wheel, and contacts 6 are then closed to allow full power to be supplied to the motor. When switch 2 is closed to energize solenoid 1, relay windings 8, 11 are also energized but neutralize each other. When contacts 3 are closed, the current through winding 11 is reduced but relay winding 12 is energized so that windings 11, 12, together neutralize winding 8. Closure of contacts 6 short-circuits the winding 11, but the current in the winding 12 is sufficient to neutralize the winding 8 as long as the engine has not started. As soon as the engine starts, the current in winding 12 is reduced, and contacts 9 open to de-energize the solenoid 1. Specification 742,024 is referred to.

Filed: 1956-12-19
Abstract: In the manufacture of polymers, e.g. polymethylene terephthalates, the viscous liquid produced is lifted in thin layers above the pool of liquid, and these are broken by other similar layers to agitate the liquid and preferably also free it from solvents.  A heated drum 1, Fig. 3, <PICT:0823100/III/1> has mounted therein two horizontal axes 4, 5 on which are mounted agitator members 8, 9 with projecting arms 6, 7, which intermesh when the axes are rotated preferably in the same direction.  The drum is divided into compartments by baffle plates 17, 18, and is provided with an inlet 13, outlet 14, and vacuum line 15.  The clearance between the intermeshing arms is about 5 mm., and between the arms and the vessel 15 mm.  In operation, the arms lift a curtain of the viscous polymer, which is broken by the similar curtain lifted by the intermeshing arm, thus aiding final polymerization.  The drum may be tilted to assist flow towards the exit, and the rotating arms may be raked to urge the material forward.ALSO:In the manufacture of linear polymers, e.g. polymethylene terephthalates, the viscous liquid produced in the final stages of polymerization, is lifted in thin layers above the pool of liquid, and the layers are traversed and broken by other layers to expose a large surface of liquid and free it from solvent. A heated drum 1, Fig. 2, has mounted therein two horizontal axes 4, 5 rotating in the same direction and provided with agitator members 8, 9, having arms 6, 7 which intermesh with a small clearance of about <PICT:0823100/IV (a)/1> 5 mm.

Abstract: 1,061,437. Cigarette making machines. K. KÍRBER. Oct. 7, 1963 [Nov. 17, 1962], No. 39385/63. Heading A2C. In a method for rearranging parallel rows of rod-like articles, such as cigarette filters, in a direction transversely to their axes in transit from a receiving point to a delivery point, the articles of each row successively receive a relative movement transversely to their axes exclusively at the transfer point. Apparatus for carrying out the method comprises an intermediate conveyer 1 rotatably mounted between a magazine drum 2 and a grooved drum 3. The conveyer 1 consists of three discs 1a, 1b 1c having engagement faces 4a, 4b and 4c offset to each other by an amount equal to the pitch of the grooves on the receiving drum 3, consecutive faces on each disc having a pitch of three times that of the grooves on the drum 3. Cigarette filter lengths are fed from a magazine 6 by oscillating rotary rollers 10, 11 to the magazine drum 2 which consists of six grooved discs 2a-2#, the discs 1a, 1b and 1c entering between the discs 2a and 2b, 2c and 2d, and 2e and 2# respectively. Each filter length is cut into three double length filters by disc cutters 29, 30. The discs 1a-1c are of progressively slightly larger diameter and are mounted for rotation on a common stationary shaft by means of eccentric support bushes providing rotary bearings for the discs. The discs are driven by a dog clutch coupling and are coupled together by pin and slot connections. The circles K1, K2, K3 swept out by the discs 1a, 1b, 1c, respectively coincide at the point B where the filters are delivered to the drum 3. The arrangement and speed of rotation of the discs 1a-1c and drum 2 are such that whilst the drum 2 moves a distance corresponding to the distance between successive grooves the three longitudinally aligned cut filters in the groove at the point A are successively taken by the faces 4c, 4b and 4a each one being successively delivered to a groove in the drum 3 for subsequent alignment into an in-line row.
